Some people deal with confidential files and use Dropbox for these. It would be very useful to allow people the option to clear their "Recent" files at will to allow more privacy and discretion.
From all what I read I understand that Dropbox is another information collector. They act as Whatsapp, Facebook (now the owner :-)), Google, to name some. Please stop this attack and stay apart from those that sell "cheap" environments at the price of collecting private and confidential information.
